From: Google Health Trends performance reflecting dengue incidence for the Brazilian states

Fig. 4

Logarithm of Internet users and Google Health Trends adjusted R squared. Maps (right panels) depict the adjusted R squared statistic per state when assessing Google Health Trends with their corresponding dengue incidence (linear regression plot). Twelve of 27 states showed values above 0.8 (top, dark blue). The logarithm of Internet users shows that the majority of the Brazilian states with high numbers of Internet users were concentrated at the southeast of Brazil (bottom, dark blue), but the remaining states show limited Internet penetration (pale green). Some states showed low number of Internet users but high GHT data fit (e.g., Amazonas, Maranhão, Paraiba, Distrito Federal). Maps were created with shape files from https://www.naturalearthdata.com/. Abbreviations of Brazilian states: AC: Acré, AL: Alagoas, AP: Amapá, AM: Amazonas, BA: Bahia, CE: Ceará, DF: Distrito Federal, ES: Espírito Santo, GO: Goiás, MA: Maranhão, MT: Mato Grosso, MS: Mato Grosso do Sul, MG: Minas Gerais, PA: Pará, PB: Paraiba, PR: Paraná, PE: Pernambuco, PI: Piauí, RJ: Rio de Janeiro, RN: Rio Grande do Norte, RS: Rio Grande do Sul, RO: Rondônia, RR: Roraima, SC: Santa Catarina, SP: São Paulo, SE: Sergipe, TO: Tocantins
